    摘要： A filter and filter material for providing or treating potable water is provided. The filter includes a housing having an inlet and an outlet, a filter material disposed within the housing, the filter material formed at least in part from a mixture of a plurality of mesoporous and microporous activated carbon particles. Preferably, at least some of the mesoporous activated carbon filter particles are coated with a cationic polymer, and even more preferably, at least some of the particles are coated with a cationic polymer and silver or a silver containing material. Kits comprising filters and information relating to the reduction, killing or removal of bacteria, viruses, microbials, and TTHM are also provided.

    摘要： In one embodiment, the present disclosure provides fail-safe mechanisms for final filters. The fail-safe mechanisms of the present disclosure include a prefilter that is essentially transparent or translucent to TOC contaminants and a microporous filter downstream from the prefilter that filters contaminants by means of size-exclusion, mechanical interception, coagulation, or a combination thereof, the filter being adapted to significantly reduce fluid flow and undergo blockage under a challenge by TOC contaminants. In another embodiment, the present disclosure provides a method of filtration that includes the steps of providing a microporous filter disposed upstream from a final filter, the microporous filter capable of filtering contaminants from a fluid by means of size-exclusion, mechanical interception, coagulation, or a combination thereof, and said filter being adapted to significantly reduce fluid flow and undergo blockage under a challenge by TOC contaminants, and filtering the fluid through the microporous filter
